Decouple footnotes from main text [duplicate]

Question

I have a few sentences with a lot of footnotes. Currently my tex code looks like this:

This is One%
%
\footnote{
Footnote text 1
}%
%
, Two%
%
\footnote{
Footnote text 2
}%
%
~and Three%
%
\footnote{
Footnote text 2
}%
%
.

The code is obviously very hard to read and also error prone with regard to the commas, points and whitespaces following the footnote. I have added the comment lines for better readabilty, but it only helps a little bit. Is there a way to decouple the footnotes from the main text? I know that there are the commands \footnotemark and \footenotetext, but when I write

This is One\footnotemark, Two\footnotemark and Three\footnotemark.

\footnotetext{
Footnote text 1
}
\footnotetext{
Footnote text 2
}
\footnotetext{
Footnote text 3
}

all the footnote texts refer to the last footnotemark. I also know that I could use the number parameter (and thereby making the footnote indexes static), but then I would get a problem if I have to add footnoes before or between the existing footnotes. How can I achieve a code like in the second example, but at the same time keep the footnote indexes dynamic?

Answer 1

The \footnotetext macro is basically meant for referring to a \footnotemark, rather near to it, using the current value of the footnote counter, however, multiple \footnotemark will increase the footnote counter accordingly, i.e. in the example it has the value of 3.

Now, \footnotetext will use only 3 as counter value, not the previous one.

A workaround is to reset the footnote counter and automatically step the footnote counter each time \footnotetext is used, by using \xpretocmd (prepending the command with a \stepcounter)

\documentclass{article}

\usepackage{xpatch}

\xpretocmd{\footnotetext}{\stepcounter{footnote}}{}{}

\begin{document}



This is One\footnotemark, Two\footnotemark and Three\footnotemark.


\setcounter{footnote}{0}
\footnotetext{%
Footnote text 1
}
\footnotetext{
Footnote text 2
}
\footnotetext{
Footnote text 3
}


\end{document}

Update

Another approach, somewhat reinventing endnotes:

\documentclass{article}


\usepackage{xparse}

\ExplSyntaxOn

\seq_new:N \g_rolch_seq 

\NewDocumentCommand{\StoreNote}{+m}{%
  \seq_gput_right:Nx \g_rolch_seq {{#1}} % Storing all notes in a list
}

\NewDocumentCommand{\ShowNotes}{}{%
  \setcounter{footnote}{0}
  \seq_map_inline:Nn \g_rolch_seq {\stepcounter{footnote}\footnotetext{##1}}
}


\ExplSyntaxOff


\AtEndDocument{%
  \ShowNotes%
}


\usepackage{blindtext}

\begin{document}


This is One\footnotemark, Two\footnotemark and Three\footnotemark.

\StoreNote{A long note}
\StoreNote{Another Long note}
\StoreNote{The note for the footnote with number \number\value{footnote}}

\blindtext[5]

Another\footnotemark

\blindtext[6]

Another footnote anchor is here\footnotemark


\StoreNote{More long notes}
\StoreNote{More other long notes}
\StoreNote{And now for something completely different}





\end{document}

Answer 2

Here I develop what amounts to a labeling system for footnotes. Define them in the preamble with \labelfn{label}{footnote} and recall them in the text with \Lfn{label}.

\documentclass{article}
\newcommand\labelfn[2]{\expandafter\def\csname Footnote#1\endcsname{#2}}
\newcommand\Lfn[1]{\footnote{\csname Footnote#1\endcsname}}
\labelfn{intro}{This is my introductory footnote.}
\labelfn{trivia}{Here is a bit of trivia.}
\labelfn{reminder}{Now for a reminder.}
\begin{document}
\vspace*{6in}
Here is some blah-blah text.\Lfn{intro}  Now as I continue my
text, there is more\Lfn{trivia} to say on the subject.

I am now done.\Lfn{reminder}
\end{document}
